The PQ3K is a cost effective monitoring solution that combines general purpose PQ detection (with waveform recording) and 4 quadrant energy monitoring in one instrument. Wide-ranging applications include utility, facility, manufacturing, petro chemical, mission critical and more.

The PQ3K is housed in a 144mm x 144mm panel mounted enclosure with a high resolution, color TFT display.

Traditionally, power quality monitoring is only conducted as a reaction to trouble such as device failure, plant malfunctions, process interruptions or communication breakdowns. However, all these problems cost money and nobody wants to experience the same thing again just to be able to create a corresponding record for analysis. Therefore, the biggest advantage of continuous power quality monitoring is that users put themselves in a position to proactively build up their knowledge thus increasing system availability.

DRANETZ PQ3K / PQ5K helps to detect trouble before it can do any damage and to provide data for the identification of the root cause in case an event actually occurs.

DRANETZ PQ3K / PQ5K is a Class A device according to the IEC 61000-4-30 Ed.3 power quality standard. It can thus provide reliable and comparable information for regulatory agencies, negotiations with energy suppliers or internal quality control.

Conformity reports on various standards can be generated directly via the website of the device.
